Dust and smoke processing system

Abstract

The invention relates to a dust and smoke processing system which comprises a dust and smoke processing subsystem and a circulating water processing subsystem. The two subsystems are connected through a pipeline. The dust and smoke processing subsystem comprises a spraying absorption device, a whirlwind dewatering dust removal device, a viscous matter impact capturing device, a dust and fog drop filtering device, a cooling and condensing device and a vapor filtering device which are sequentially connected. The circulating water processing subsystem comprises a primary deposit processing device, a grid primary filtering processing device, a deposit filter processing device, an air floating processing device, a quartz sand filtering device and an activated carbon adsorbing device which are sequentially connected. The dust and smoke processing system has comprehensive functions of dust removal, smoke removal, fog removal and vapor removal, and the sufficient processing of industrial dust and smoke pollution is achieved.

Description

technical field [0001] The invention relates to the technical field of environmental protection treatment, in particular to a smoke dust and flue gas treatment system. Background technique [0002] At present, air pollution is very serious. Industrial smoke and dust are one of the important sources of pollution. They mainly come from two ways: combustion and drying; increasing the height of the chimney is not to solve the problem but to avoid the problem, so the smoke and smoke must be treated before discharge. fully processed. For example, various industrial boilers such as power plants, although large-scale boilers have undergone desulfurization and denitrification treatment, most of these treatment processes use the GGH system to intentionally increase the discharge temperature in order to prevent corrosion of chimneys and other pipes, resulting in a large amount of emissions. Haze, so it is necessary to carry out advanced treatment or increase the corresponding treatmen...

Problems solved by technology

For example, various industrial boilers such as power plants, although large-scale boilers have undergone desulfurization and denitrification treatment, most of these treatment processes use the GGH system to intentionally increase the discharge temperature in order to prevent corrosion of chimneys and other pipes, resulting in a large amount of emissions. Haze, so it is necessary to carry out advanced treatment or increase the corresponding treatment process; for example, the drying and drying of industries such as wood-based panels and glass fibers produce a large amount of high-temperature organic harmful gases and moisture. Although some factories have also done some treatment, but The result of the processing is basically not in place, especially in autumn and winter, white smoke is still flying
